WASHINGTON — In a stunning break with First Amendment policy, House Republicans directed Capitol Hill police to detain a highly regarded documentary crew that was attempting to film a Wednesday hearing on a controversial natural gas procurement practice. Initial reports from sources suggested that an ABC News camera was also prevented from taping the hearing; ABC has since denied that they sent a crew to the hearing.

Josh Fox, director of the Academy Award-nominated documentary “Gasland” was taken into custody by Capitol Hill police this morning, along with his crew, after Republicans objected to their presence, according to Democratic sources present at the hearing. The meeting of the House Subcommittee on Energy and Environment had been taking place in room 2318 of the Rayburn building.

HuffPost has obtained exclusive video of the arrest of Josh Fox. Rep. Brad Miller (D-N.C.), the ranking Democrat on the subcommittee, can be heard at the end of the clip asking Republican Chairman Andy Harris (R-Md.) to halt the arrest and permit Fox to film the public hearing. Harris denies Miller’s request as Fox is escorted out of the hearing in handcuffs.
